I'm 8-1/2 months clean and sober and I get the hangover feelings from time to time. Had one a few days ago. I think for me they are mainly emotional hangovers. If I get overly stressed or have a problem I dont take care of real quick, I have an emotional hangover. However, sometimes when I get together with friends and drink a few cups of coffee and eat a bit of sweets at night, I tend to have a morning hangover.
When I use the term "hangover" nowadays, it's no where near the alcohol hangovers I use to have.
Thank you God,
MIchael
